Suspension: the world's first suspension with "eyes"





The new S-Class is the world's first car to be able to detect bumps on the road ahead. If ROAD SURFACE SCAN detects such unevenness by means of the stereo camera, MAGIC BODY CONTROL instantaneously sets up the suspension to deal with the new situation. This innovative suspension system is available as an option for the eight-cylinder models. Standard equipment for the new S-Class includes the continuously operating Adaptive Damping System ADS PLUS and an enhanced version of the full air suspension system AIRMATIC.

Rock You Like a Huracan

In the motoring world, success is perhaps more difficult to follow than failure— at least if you fail a blank sheet is the obvious choice. When you’re trying to better your past triumphs, it gets a bit sticky. Which is what Lamborghini was looking at with the Huracan, their follow up to the best-selling Lambo in the history of the marque: the mighty Gallardos. And the sales of that car were mighty too, the Sant'Agata-based carmaker sold 14,022 Gallardos over a decade of production— that’s more than 50% of Lamborghinis sold, er, ever.
So if the Gallardo was such a roaring success, why change at all? Well, technology moves at a break-neck pace and the Gallardo, at least in terms of specs, had been eclipsed by the Ferrari 458 and McLaren’s 650S— after all, at the uppermost echelons of the supercar game, it’s always an arms race. To stay abreast of the competition, Lamborghini’s V10 formula would have to bring big numbers, or simply stay home. Which option sounds more Lambo-like to you?

The Huracan rolled out with an all-new chassis structure, revised suspension with fresh controlling electronics, new steering, and a decisively updated engine. They also replaced the outgoing car’s robotised manual tranny with a modern seven-speed dual-clutch gearbox, which might have had the greatest delta effect on the car’s driver experience. The interior is new, the four-wheel drive is new, the only thing that remains relatively consistent is the exterior design because, well, Lambo clearly recognized that the Gallardo design was a powerful attractor and sought to bathe in that glow with the Huracan, while blowing the occupants hair bask all the harder.

The Huracan uses RTM carbonfibre for its central tunnel, rear bulkhead, and the rear part of the sills— much like the McLaren is sought to better. Like the 458, the car relies on aliminium from the rear bulkhead backwards and, like both those aforementioned benchmarks, the frame is aluminium based. There’s more aluminium forward of the windscreen forwards, and the lightweight alloy graces the while body panels as well. All that works adds up to a chassis that is 50 per cent more rigid than it’s predecessor, while managing to winnow the weight down 10 per cent.

And while the name Huracan conjures up images of severe blowing, the car’s 5.2-litre V10 is naturally aspirated because, come to think of it, what’s more naturally aspirated than a hurricane? Even with out the Hell Cat treatment, this V10 routes 602bhp to all four wheels through the car’s zippy new transmission, handling the 0-100kph gust in 3.2sec, entering the 200kph slip stream in just 9.9secs. Oh, and the power plant sounds like mayhem’s soundtrack, thundering through the valley (or dunes) with a pure exhaust note for the ages.
What else is superlative in this supercar? The torque curve is epic, serving up about three quarters of the Huracan’s 413lb ft from 1000rpm, which speaks very well of this turbo-free design. At its 1422kg kerb weight, the car boasts a power to weight ratio of 423bhp per tonne, which bettered the 458 and nearly matched the 12C.

Outside, this is the more conservative member of the Lamborghini fleet (doesn’t that phrase call an awesome image to your mind?), and rightfully so since they expect to sell the most of them. The Veneno, Aventador and the Sesto Elemento, offer a more obvious assault on the senses, but the Huracan is well, a tad subtle for a supercar in the way that Bach is subtle compared to, er, Niki Minaj. OK, so I’ve overstated my point— it’s just that unlike some of the most cutting edge designs on offer from the likes of McLaren, Lambo, and Hennessy (to name a few) the Huracan doesn’t look like it’s actively trying to kill you.

Settle into the driver's seat and the guts will be familiar to the Gallardo initiated. You can’t see much out the back, but then, that’s more or less to be expected in a car like this. Everything inside the cabin is geometric and bold, and the overall fit and finish is eons away from the good-old-bad-old days on Lambo building. You get the same full-TFT screen seen in the Audi TT, graphically re-imagined for Lamborghini and configurable for tracking the rev counter, speedo or nav. Not too many buttons clouding the horizon here, and many daily use functions like indicators and wipers now actuate from the steering wheel.

But by far the most interesting control is the ‘Anima’ (or soul) button at the bottom of the wheel, which toggles between three settings: Strada, Sport and Corsa. Press the Anima button and the dampers, dampers, steering and traction settings, all adjust, while Strada and Sport ramp up overrun burbles to a flatulent fury.

In practice, the Huracan is an absolute track weapon, that likes nothing better than to run all the way up to 8500rpm with gusto. The suspension is limber, bot not overly so, and inspires coincidence as you build speed. The shifts are worlds-better than the Gallardo too, whipping through the gears like a hot knife to butter, and not particularly tempting this pilot to paddle at all.

The Huracan’s stability system is informed by some choice aeronautical tech, combining of three accelerometers and three gyros to help keep the car’s pitch, roll, and yaw in check. The carbon ceramic brakes do an admirable job of halting the fleet-footed beast, and that’s a bit of comfort considering how fast this thing is. Additionally, the active electric steering, which varies in rate depending upon ‘Anima’ setting, feels great and makes it that much easier to hone in your lines.

Some might have worried that sitting out the charge towards, er, turbochargers, might have put the Huracan at a disadvantage— not so. This V10 is a masterwork, not only keeping the competition on their toes in the spec wars, but delivering on that all important Lamborghini DNA— something that, last we checked, you can only get in a Lambo. Add the much improved transmission, four-wheel drive, excellent stability systems, and you can see why the Huracan can rock your world like the proverbial hurricane.

AUSTIN DILLON ON DAYTONA WRECK, 'YOU FEEL LIKE SUPERMAN'






DAYTONA BEACH, Fla. -- Dale Earnhardt Jr. won the Coke Zero 400 early Monday morning, but
the finish of the race was marred by a horrifying crash that sent Austin Dillon's car sailing into the catchfence at Daytona International Speedway. Dillon walked away and waved to the crowd after his car got airborne and was torn apart by the fence. He was been checked and released from the infield care center with a bruised tailbone and forearm. Track president Joie Chitwood III confirmed 13 fans were examined and eight declined treatment. Of the five treated, one was transported to a local hospital, treated and released. The other four were treated at the infield care center. "It's not really acceptable, I don't think," Dillon told reporters after exiting the care center. "We've got to figure out something. Our speeds are too high, I think. I think everybody could get good racing with slower speeds. We can work at that, and then figure out a way to keep the cars on the ground. That's the next thing. We're fighting hard to make the racing good. I hope the fans appreciate that. We don't, but it's our job. You go out there and hold it wide open to the end and hope you make it through."

Nissan GT-R NISMO 2015












The 2015 model year marks the seventh for the GT-R, and nearly every turn of the calendar has come with incremental updates from Nissan, stretching the envelope of a car we initially called “big, heavy, and incredible.”
The portfolio grows this year to include a NISMO—Nissan Motorsports—model, and all three of our initial adjectives still ring true. NISMOizing the GT-R makes it a little bigger, stretching the car’s length by 0.5 inch with new bodywork. This includes an integrated splitter and a raised rear wing that, according to Nissan, increase
.downforce at 186 mph by 220 pounds without affecting the car’s 0.26 drag coefficient



At 3883 pounds, the NISMO is still a heavy beast and only a scant two pounds lighter than a 2014  GT-R Track edition. With engine modifications—including larger turbos lifted from Nissan’s FIA GT3 racers, remapped timing, and revised breathing—the 3.8-liter V-6 produces an additional 55 horsepower and 18 pound-feet of torque, for 600 and 481, respectively. Reportedly, Nissan could have cranked it up even further, but resisted the urge for the sake of transmission longevity, which is a touchy subject after early R35 models Cuisinarted their transaxles
A quarter-mile run doesn’t reveal much difference from the ’14 Track model, with the NISMO breaking the tape in 11.2 seconds at 125 mph. That’s the same time and just one mph swifter than the ’14. In fact, the two track sheets look eerily similar. Both cars register 1.02 g’s on the skidpad, stop from 70 mph in 145 feet, and sprint to a mile-per-minute in 2.9 seconds. Maybe the tires and drivetrain are just about maxed out in the launch department. The NISMO’s extra power is apparent mainly in its run to 130 mph, which is 0.3 second quicker than the Track 
                      model’s time

Adjustable Bilstein dampers, revised springs, and a hollow anti-roll bar at the rear crank up the GT-R’s stiffness. This is no commuter; when it comes to ride quality, think Porsche 911 GT3 RS or a chunk of granite. There are three settings for the dampers, but even in the laziest mode the chassis feels stiffer than a regular GT-R’s

If there were a prize for most alphanumeric suffixes, the NISMO’s Dunlop SP Sport Maxx GT 600 DSST CTT tires would clinch it. Developed specifically for the NISMO GT-R, Nissan claims the tires are stickier than last year’s rubber. After driving the car on a track and into a paradox with our dusty skidpad readings, we believe that claim
Understeer is the NISMO’s yeti: Hunt for it all you want, you’ll never find it. The NISMO cuts into a corner with the force of a car intended only for closed courses and pro drivers. Find the apex, mash the gas, and keep it pointed on the road. It’ll do it time and time again, without protest.
The NISMO costs a whopping $48,220 more than a base GT-R, for performance that isn’t apparent on paper. If you’re able to fully appreciate its capabilities on the track, however, you’ll exit saying “incredible, incredible,” which is twice as many times as we said it years ago. And if it isn’t blade-sharp enough for you, a NISMO track model is coming soon
